To all lwlw/m, t may concern Be it known that I, HORACE T. THoMAs, citizen of the .United States, residing at Lansing, county'of Ingham, State of Michigan, haveinvented a certainnewfand use-` ful Improvement in Apparatus for''Finishing Uphols`tering,; and declarethe following to be a full, clear, and exact description -of the same, such as will enableA others skilled in the art to which it pertains to make and use `the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to a process and apparatusv for finishingupholstering and a special object Offmy improvements is to provide fr securing the ends of the "finishing strips in automobile seats.y companying drawings, v

Figure l isa .cross section of a top of a seat illustrating my invention.

Fig. 2 is a front elevationof the saine. Fig. 3 isa section substantially on the In the ac- A plane III--IIIof Fig. 1.l

Fig. 4 is a section of Fig. 2. y

Fig. 5 is a section similar to Fig. 4 illus- Aon the line IV-IV trating vthe method of securing the finish-V curing nail passing through the strip Y) near its end and into the rail a2.

al is a finishingV tip, or ferrule, for the end of the'finishing strip. b. This ferrule is made-of sheet metal and is formedwith a ridge d2 concavewithin and concave Out- Wardly extending transversely across the top of the ferrule near its inner end. The outer Aend of theferrule is closed by the wall d3. d* d4 are wings formed by bend- -edges come approximately together. This vplaced over the'end lofthe finishing strip `rule d isiat the same time Vdriven snugly ing inward the lower side ledges .of .the ferrule. 'These wings do not cometogether 1 forthe greaterA part of their lengthbut are' extended somewhat at their rear. ends nas indicated. alt-d5 so that` atV this point the forms shoulders d, the utility ofy which will'v be `hereinafter pointed out. .o

The manipulation of Y the'above apparatus-is asfollows: f

The yfinishing .strip Z;` is first secured in position and the nail cat its end ldriven verticallythrough'said strip in to the rail a2k and nearly home. The ferruleiis then described and the wings (Z4 Z4 bent towards each other as shown in F ig; '5. A' die e havingitsend j providedwith a matrix e2 fitting over and shaped to the tip Z vis then placed over said tip and driven home with the blow :.ofa hammer on -itsouter end, thus the wings ci* ci* are closely clasped` under the end of i' the strip b between saidstrip and the rail a?, andthe nail' c which is within -the ferhome, the die 'embracing the ferrule and holding it` closely against the strip prevent- ,n ing any possible splittingof the strip. The

:ridge lZ2 .servesfto strengthen the -ferrule v and the soft Wood of the finishing-'strip ex'-, i'

tends somewhat'up into thecavity of thelfi'l ridge Z2 thus preventing thewithdrawal of" the ferrule from ,the strip. -The nail b' passes Vbetween the edges of -thewings d* d* 4 and the wood of kthe finishing ,strip Z) also engages the: shoulders d". The ferrule' d 85 can not be removed from the construction because `the shoulders Z5 will engage the nail a .and prevent suchwithdrawal;

Claims: y o 1. The combination of a vfinishing strip, a `ferrule embracing-the end of said strip,

said ferrule' being provided with Aa trans.

verse ridge having a concavity within said i ferrule for .the purpose described. i y i 2. .The combination of. a finishing strip, 95 a ferrule placed overthe end of saidstrip, said` ferrule having inwardly bent edges extending under said strip for the purposel iris.

described, said edges being shaped to forni the shoulder do.

3. The `combination of a finishing strip,

a ferrule placed over the end of said strip,

5 said ferrule having inwardly bent edges extending over sald strip for the purpose described, said edges being shaped to form the shoulder d6 and a nail passing through said strip in position to be engaged by said shoulder for the purpose described. 1U

In testimony whereof, I sign this speciication.
